WINDNG- AND TWISTING APPARATUS.

Specification of Letters Patent.

Patented liteit .Application filed May 3, 1915. Serial No. 25,336.

lle it known that l, @limites `W. llneiinn, a eitizsen of the UnitedStates, residing et 1oosten, county of Suffolk, State ofMassacln1setts,li:ive invented an Improvement in Winding and TwistingApperatus, of which the following description, in connection with theaccompanying drawing, is e specification, like Lcharacters on the drewing represimting like parts.

This invention relates to apparatus for twisting and winding yarn ofthat type in which the yarn mass is built up in layers ex* tendingTtransversely to the axis of rotation thereof. A Winding and twistingapparatus off this type illustrated in my Patent No. 1,232,6857 datedJuly l0, 1917.

The objects of .my present invention are to improve devices oit' thischaracter by simplifying the construction thereof and making; theWinding head compact, thus nmliing the apparatus capable of running atan increased speed, and also to provide a novel yarn receiver in theform of a tubular element having a bottom or yarn-support ing memberslidalgile longitudinally therein so that as the yarn mass is built upthe yarn support will be forced axially of the yarn receiver7 andotherwise to improve Winding' and twisting apparatus of this nature' allas will be more fully herein ail-ter described and then pointed out inthe appended claims. i

In order to give an understanding of my invention I have illustratedherein a selected embodiment which Will now be described.

'Figs'. 7 and ci are fragmentary@sectional views showing` dillerent'forms et yarn sup ports which may be used in the yarn receiver.

'lhe apparatus herein shown. is somewhat l-iiinilrir to that illustratedin my above-inem tieiied lzlatcnl, No. 'L2-32,685, in that it einbodiesa roterv yarn receiver l in which the yarn in l is heilt up in layerseX- tending transversely to the airis of rotation by means oi e rotarywinding plate 3 which rests on the yarn mass and is provided with ayarfrdelivery slot 4r through which the yarn 5 is leid by Ineens of avibrating yarn guide (i, the Winding plate 3 rotating at a difierenYspeed from the yarn receiver l to effect the desired Winding action.

In the present embodiment of my invention I have aimed to simplify themecha nism of the twisting head, of which the Winding plate 3 and yarnguide 6 form a part, so as to make it capable of high speed operation.The Winding plate 3 is shown as secured to the lower end of a member 'iWhich is provided With, :L transverse passage or space 8 in which theyarn guide t reciprocstes, end this member 7 is rigidly secured to ahollow spindle 9 through which the yarn 5 is led to the yarn guide (iand which is rotated at the proper speed from a 'gear l0 thereon whichmay be driven from any suitable source of power. The yarn rcceiver l isconnected to and depends from aholding element 11 having a shell-lileformation, said holding element being' secured to a sleeve or shaft 1Qthrough which the spindle 9 extends end which has fast thereon a gear 13by which. it driven. This hollow shaft orsleeve 12 is journaled insuitable bearings lll. rlhc 4gears l() and 13 are driven from anysuitable source and at the desired speeds to give the Wimling` plete 3and yarn receiver l the proper relative speed.

In order to simplify lthe construction and to provide a device capableet high speed operation I have secured the yarn guide 6 to a rocleshaft15 `which is journaled in the member 7 and extends transversely. Saidrock shaft is given its required oscillatory movement by means of a coinmember lli which is loosely mounted on a sleeve il' that eneircles thespindle 9 and is hurler-sed in the sleeve l2. The cam clement lo isprovided with a-peripheral cam groove lil in.

which is received a roll 19 carried by a v slide 20 that operates in esuitable guidevvay 21 formed in e, housing er shell-like mc1nber 22 thatincloses the cern member i6 and is secured to the member said members 22and 7 forming a chamber 23 in. which 'the cam '16 is received. Thisslide 20 is een nected"at its lower end to a crenlr arie 2t formed onthe reel -shalt'lf so thet 'vertical reciproca-ting movement eil? theslide will.

oscillate the shaft 15 thereby oscillating the yarn guide 6. The camgroove 18 in the cam member 16 is so shaped and constructed that as thecam member 16 rotates relative to the member 7, the slide 20 will begiven a vertical reciprocating movement. The

cam member 16 is gi`ven its rotary movement by differential gearingactuated partly by the spindle 9 and partly by the shaft 12. The sleeve17 isshown as having fastthereto a gear 26 which meshes with a pinion 27pivotally mounted on the member 7, and this pinion 27 also meshes with agear 28 which" with the member 7 and spindle 9, there will be a relativemovement between these gears which `will result in giving rotation tothegear 28 and cam member 16. AThe gears 26 and 28 are provided withdifferent number of teeth so that the oscillatingy rotary movement ofthe gear 28 and cam member 16 will be faster or slowerl than therotation of the shaft l2 and yarn receiver, depending on whether thegear 26 has'a greater or less number of teeth than the gear 28. Theparts 22 and" 7 t tightly together so that the chamber 23 is oil tightand thus the gears 26, 27 and 28 and the cam member 16 can be situatedin an oil chamber.

Associated with the yarn guide 6 is a compensating member 33 in' theform of'a vibrating arm having a guide eye 34 at its end through whichthe yarn 5 passes in its transit from the end of the spindle 9 to theyarn guide 6. This cmpensating arm has for its function to compensatefor the radial movement of the thread guide 6 so that the yarn will be'drawn through the spindle 9 at a uniform speed notwithstanding theoscillating movement of the thread guide 6.'

This compensating arm is given its movement by mechanism similar to thatwhich operates the yarn guide 6. Said arm is shown as fast on arocrfshaft 35 mounted iu the member 7 and extending parallel to theshaft 15, said rock shaft having a crank arm 36 thereon which islpivotally connected to a slide 37 similar to t e slide 20 andoperating' in a ideway formed in .the member 32. T iis slide 38 isprovided with 'a roll 39 operating in a cam groove 40 formed in the cammember 16, said cam groovev having such a shape as to give thecompensating arm 33 its requisite Inovement. In order to make a compactstructure I have placed the cam groove 40 within the cam` groove 18. Thecam groove 18 oughly balanced, and to provi e for main taining an evenbalance notwithstanding the reciprocating movement of the thread guide 6and compensating arm 33, I have provided a transversely-moving member 43operating in a suitable guideway and having a rojection 44 operating ina cam groove 45 ormed on the top of vthe cam member 16.r This cam grooveis properly shaped so that the member 43 will have such a relation tothe vibration ofthe arms 6 and 33 as to maintain` the twisting head intrue balance at all times. The twisting head abovevdescribed is very'compact in structure andfis Well adapted kfor highspeed operation.

In the structure herein illustrated the yarn receiver and .twisting headhave no axial movement'relative to eachother during the laying 0f theyarn mass 2, but the yarn mass is built up on a yarn supportV whichiscapable of moving axially of the yarn receiver 1 as the yarn massaccumulates. This yarn support is shown at 4.5 and it is constructed tohave frictional engagement with reciprocating movement of the balancing1 the'walls of ythe yarn receiver so as to prol vide suliicientresistance to the movement of the yarn mass to insure that the yarn willbe compactly laid. This yarn support 45 may be constructed in variousways'without departing from my invention. In Figs. 1 and 6 I haveV shownit as formedin two sections 46 and 47 which are yieldingly pressedagainst .the walls of the yarn receiver 1 by means oitwo springs 48.These sections 46 and47 may be made of wood or any other suitablematerial and both sections are shown as provided with alined transverserecesses 49 in which a spring-receiving tube 50` is received, the sprmgs48 being mountedin said tubes 50. One end of eac spring bears againstthe end wall 51 of` the recess 49 in the member 47, and the other end ofthe spring bears against the plug 52 screwed into the. end of the sleeve49. Said springs thus tend to separate the members 46 and 47 and toyieldingly hold them against the walls of the yarn receiver 1. This yarnsupport 45 is a reversible one and is provided on each face with alayer53 of felt or similar material that will :furnish a propervfrictonalanchorage for the yarngat `the beginning of the winding' operation.,y,As the .yarn n 1ccumulates, the yarn support 4 it forced teken by :mem pty hold 1 ,$3 litigi; Il. ll
